NOZZLE HANDLE.

Application filed September 28, 1926. Serial No. 137,209.

The present invention relates to nozzle handles. v

More particularly the present invention relates to handles suitable foruse in elongated cleanin guns of the type shown and described in TatentNo. 1,461,824, granted July 17th, 1923, to the present applicant.

An object of the present Invention 1s to provide an improvement over theconstruction disclosed in the patent above referred to in whichthe-valves will be held against displacement from their properpositions.

A further object is to provide a construction involving no more cost inmanufacture and assembly than is involved in the construction disclosedin the patent above referred to, which construction will efi'ectuallyhold the parts in predetermined 13031131011:

Further objects will appear as the description proceeds.

Referring to the drawings- Figure 1 is a view in side elevatlon of acleaning gun having as one of its constituent parts a handle embodyingthe principles of the present invention;

Figure 2 is a longitudinal sectional VIQ'W of a portion of theconstruction shown 1n Figure 1; and

Figure 3 is a transverse sectional view taken along the plane indicatedby the arrows 3-3 of Figure 1.

The numerals 10 and 11 indicate two pipes disposed in parallelrelationship with one another, which pipes are connected at their outerends to the nozzle 12. The pipes 10 and 11 are adapted to delivercleaning mecha to said nozzle 12, which media are mixed in said nozzleand discharged therefrom against an object to be cleaned. The inner endsof said pipes 10 and 11 are mounted in a handle, indicated as a whole bythe numeral 13, which handle forms the subject matter of the presentinvention. Flexible tubes 14 and 15 are provided for delivering cleaningmedia to said pipes, valves 16 and 17 being provided for governing therate of flow from. said flexible tubes 14 and 15 to said pipes 10 and11. Short connection pipes 16 and 17 connect the flexible tubes 14 and15 to the valves 16 and 17, respectively. I y

The handle 13 is made up of two major portions 18 and 19 adapted to befitted together and to provide supports for the valves 16 and 17, thepipes 10 and 11 and the connection pipes 16 and 17. The ortion 18 of thehandle 13 is provided with the hand hold 20, which is disposed upwardlyof the handle 13. The forward part of the handle portion 18, whichforward portion is indicated by the numeral 21, is provided withapertures'22 and 23 adapted to receive more or less closely the pipes 10and 11. Extending rearwardly from the forward portion 21 of the handle1.3 are the side walls 24-24, which side walls receive between them theportion 19 of the handle 13. Said portion 19 is provided with thelaterally extending shoulders 25-25 for receiving the lower rearextremities of the side walls 24-24. Screws 26-26 are provided forholding the portions 18 and 19 and the handle 13 rigidly together.

The portion 19 is provided with the apertures 27 and 28 for receivingthe pipes 16 and 17, respectively, which pipes have screw-threadedengagement wit-h the valves 16 and 17, respectively. The flexible tubes14 and 15 are joined to the pipes 16 and 17*, respectively, throughunions 29-29, which unions in and of themselves present no novelty andtherefore need not be described in detail. It will be sufficient tostate that said unions 29-29 provide abutments against the rear face ofthe portion 19 of the handle 13, whereby the valves 16 and 17 may bedrawn into'clamping engagement with the forward face of the portion 19of the handle 13.

The valves 16 and 17 may be of the regular commercial type, havingnon-round bosses at their extremities. Such bosses are indicated on thedrawing by the numerals 32-32, the usual hexagonal bosses beingillustrated. According, to the present invention, the forward face ofthe portion 19 of the handle 13 is provided with recesses 33-33conforming to the outline of the bosses 32-32 of the valves 16 and. 17.

The numeral 34 indicates a sliding hand grip mounted upon the pipes 10and 11. The operator will control the gun by gripping the members 20 and34.

As is apparent from the drawings and from the above description, thevalves 16 and 17 are rigidly connected to the portion 19 of the handle13 by reason of the clamping action of the unions 29-29 in cooperationwith the bosses 32-32 of said valves 16-17. By reason of the fact thatsaid bosses 32-32 are non-round in conformation, and inasmuch 'as saidbosses are set into recesses 33-33 which conform to the outline of saidbosses, said valves will be held against turning movement relative tothe portlon 19 of the handle 13. The portion 18 of the handle 13 may bereadily assembled relative to the portion 19 in a manner which will beclear from the drawings and from the description above, therebyproviding a rigid handle construction which effectually prevents theturning of the valves 16 and 17 under service conditions.

Though a preferred embodiment of the present invention has beendescribed in detail, it will be clear that many modifications will occurto those skilled in the art. It is intended to cover all suchmodifications that fall within the scope of the appended claims.

What is claimed is- 1. In handle construction, in combination, a portionprovided with a pair of apertures, said portion having non-roundrecesses on one side thereof at the extremities of said apertures andvalves communicating with said apertures and having non-round endportions conforming to said non-round recesses, said handle constructionhaving another portion provided with apertures aligned with said firstmentioned apertures whereby to support pipes connected to said valves,said first mentioned portion being provided with means including unionsdisposed on the opposite side of said portion rom said valves forclamping said valves in predetern'iined position relative to said firstmentioned portion and to connect said valves to sources of fluid supply.

2. In combination, a handle, a pair of valves mounted therein andadapted to be connected to a pair of pipes, each of said valves beingprovided with a non-round end portion fitting within a correspondingrecess in said handle and means including unions cooperating with saidvalves to clamp said valves in said handle to prevent displacement ofsaid valves under service conditions and to connect said valves tosources of fluid supply.

3. A handle comprising, in combination, two separable portions havingaligned apertures, valves mounted in said handle in line with saidapertures, said valves having non round ends adapted to fit withincorresponding recesses in one of said portions, said one portion beingprovided with unions disposed on the opposite side of said one portionfor clamping said valves in predetermined position relative to said oneportion and to connect said valves to sources of fluid supply.

Signed at Chicago, Illinois, this 15th day of September, 1926.
